POP-UP WASTE-VALVE MECHANISM.

Specification of Letters Patent.

Patented Feb. 28, 1922.

Application filed .Tune 22, 1921. Serial No. 479,566.

To all 'wiz-0m t may concern.'

Be it known that I, JAMES ALLINGHAM, a citizen of the United States,residing at Chicago, in the county oi Cook and State of Illinois, haveyinvented certain new and useful improvements in Pop-Up laste- ValveMechanisms, of which the following is a specification.

This invention relates to waste valve mechanisms in general, but moreparticularly to that type of such` mechanisms known to the trade aspop-up waste valves, and used in conection with wash basins and thelike.

The principal object of the invention is to provide a. mechanism foractuating the valve of the same to open or close the waste vent or pipeleading from a basin or water containing receptacle, -which shall besimple and inexpensive in construction, strong, du-

rable and eflicient in operation.

.Another object ofthe inventions is to afl'ord mechanism actuatedconveniently from a position above the top of the wash basin or abovethe slab of aV lavatory near the water faucetsv and by means of whichthe valve closing the orifice in thebottom of' the basin or the like maybe adjusted either to open the waste pipe permitting the ready dischargefrom the basin, or to close the same effectively.

Still another object of the invention is to afford mechanism which maybe readily adjusted to suit different depths and diameters of basins,and which may be readily applied to lthe basin without the assistanceof' skilled labor.

Other objects and advantages of the invention will be disclosed in thefollowing description and explanation.

The invention consists .in certain peculiarities of the construction,novel arrangement and combination of the various parts thereof as willbe hereinafter more fully set forth and specifically claimed.

In the accompanying drawing, which serves to illustrate an embodiment ofthe invention- Fig. 1 is a central vertical sectional view through thevalve casing and the cage for the valve, but illustrating the valveitself and the connections for raising the same, in elevation. This viewalso shows in dotted lines a portion of a wash. basin and a part of awaste pipe leading from the casing in drawing.

about the positions they will occupy when the mechanism is lined to thebasin.

Fig. 2 is a bottom plan sectional view taken on line 2N2 of' Fig. 1.

Fig. 3 is a vertical sectional view oi the lower portion of the valvecasing showing a modification in the construction of the means forlifting the valve of the casing, and

Fig. e is a plan sectional view taken on line 4--4 of Fig. 3.

Like numerals of reference refer to corresponding parts throughout thedifferent views of the drawing.

The reference numeral 7 designates the valve casing of the mechanismwhich is barrel shaped or has its walls outwardly bellied as showninFigs, 1 and 3 of the This casing .is internally screwthreaded at itsupper ends and provided at said end with an annular fiangc 8 to lieunder the basin 9 between the lower surface of which and the uppersurface of the flange 8 a gasket 10 of any suitable material may beinterposed to prevent leakage, The lower portion of the casing 7 isprovided with a laterally extended chamber casing 11 which is providedin its lower portion or horizont-al floor 12 with an opening 13 aroundwhich is located a stuifiing box 1a of the ordinary or any well knownconst1.uct-i m.

The lower end of the casing 7 is provided with a screw-threaded opening15 into which one end of a waste or discharge pipe 16 may be screwed orfitted, and which pipe, as usual, is provided with a trap, not shown,'which trap is usually located at that side of the valve casing on whichthe chamber casing 11 is formed.

Located in the discharge opening 17 of the basin 9 is a tubular cage 18which has at its upper end an outwardly disposed annular flange 19 torest in the upper surface of the orifice 17 of the basin. The sleeve orcage 18 is externally screw-threaded in its lower portion and said partis screwed into the upper screw-threaded opening of the valve casing,when it is obvious that the flanges 8 and 19 on the casing 7 and cage 18respectively will securely clamp the fixture onthe basin 9 and thegasket 10 when the latter is employed. By this arrangement it ismanifest that the valve casing and its cage 18 can be readily adjustedto basins of different thicknesses, and that the manner of securing themin place on the basin is so simple that skilled labor will not berequired.

Mounted in the cage 13 for vertical move` ment therein is a valvecarrying body or plug 20 which has on its upper end a closed valve head21 of a size and shape to correspond with the seat 22 therefor in theupper end of the cage 18. The valve body or plug 2O is extendeddownwardly from the valve or head 21 withinthe upper portion of thecage, and said body is by preference provided with a series of spacedvertical ribs 23 to slidably contact with the walls of the cage. Betweenthe ribs 23, the valve body is provided with longitudinally extendedconcave cavitiesl 24 which extend from the valve head 21 downwardly andafford channels for the passage of water from the basin. The body 20terminates at its lower end in a tubular extension 25 which isinternally screw-threaded to receive in its lower end a screw-rod 26which can be held in its adjusted position by means of a binding nut 27located on said rod so as to contact with the lower end of the extension25 of the valve body. This screw-rod 26 has near its lower end anenlargement or annular flange 2S to rest on the upper surface or tocontact with the upper surface of a horizontally disposed linger 29, andat a suitable distance below said flange, with a pin or vprojectionextends horizontally therefrom.

The inner end of the linger 29 is provided with an open-ended slot 31which communicates at its other end with a vertical opening 32 in saidfinger for the reception of the lower end of the rod 26, which operationis without screw-threads as is shown in Fig. 1 of the drawing. The slot31 in the finger 29 is of suflicient size to permit the pin orprojection 30 on the screw-rod26 to pass therethrough. The outer end ofthe finger 29 is extended into the chamber casing 11 and has verticallyattached thereto, preferably by being screwed into a suitable openingthereof, a vertically disposed arm 33, which extends through the opening13 in the bottom of the chamber casing 11 and through the stalling box14 thereon.

By the foregoing arrangement, itis apparent that, assuming the valvevbody is raised to such a position that the lower end of the screw-rod 26carried Vthereby will be located above the finger 29, and that saidlinger shall be dis osed directly under the lower end ofthe ro 26, bylowering the valve body, the lower end of the rod 26 will engage theopening 32 in the finger 29, when, by turning the valve body and saidrod until the pin or projection 30 on the rod registers with the slot 31in the finger 29, the rod 2O will pass further through the opening 32 ofthe finger until the flange or enlargement 28 of said rod rests on'tlieupper which surface of the linger'. lVhen in said position, it ismanifest that by turning the valve head and rod26 the pin 30 will engagethe lower surface of the linger 29 and thus prevent accidentaldisconnection of said parts,

yet a very simple and eicient loose connection, therebetween will beafforded, to the end that, when desired, the said parts may bedisconnected, .y

Pivotally secured to the outer or lower end of the vertical rod 33, isone end of a lifting arm for the finger and the valve, which lifting armor member is designated as a. whole by the numeral 34, and is extendedlaterally from the rod 33 and valve casing and mainly, horizontallytherefrom. As before stated, the waste pipe section 1G, leading from thelower end of the casing 7, is provided with a trap which is located nearthe lower portion of the casing 7 adjacent the chamber casing 11thereof, and as this trap would interfere with the vertical movement ofthe lifting arm 34, if ysaid arm was ex tended throughout its entirelength horizontally from thelower end of the `rod 33,A

l provide the arm 34 with two right angled bends 35 and 36 located in avertical plane one above the other.v This construction. of the arm 34will permit ofthe disposition and vertical operation of the' lowerhorizontal position of the arm 34 within the downward bend of the pipe16 between its upper portion and its trap, and at the same time willdispose its ripper horizontal portion and its coupling with a verticallydisposed operating rod 37, above the trap for uninterrupted verticalmovement.V 4 Y The coupling for the arm 34 and operating rod 37,consists of two sleeves 38 and 39 disposed upon and across each other atright angles and suitably fixed together. The arm 34 extends through thesleeve 38 and is adapted to be adjustablyv engaged therein by means of aset screw 40. The'operating rod 37 extends into the sleeve 39 and isengaged by a set screw 41, thereby affording a very rigid connectionbetween the yarm 34 and rod 37 but permitting either to be adjustedrelative to the other to maintain a suitable angular relation with eachother. fThe operating rod 37 is extended at its upper endthrough. asuitable opening in the stand or support for the basin and may besupported thereon in any suit-able manner. i 1

In Figs, 3 and 4 of the drawing, I have shown a modification in theconstruction of the lifting finger for the valved body, and also in themeans carried by said body for loosely connecting the finger to saidmeans. In this modification, a finger 42 is mounted in screw engagementwith the upper end of the vertical rod 33 and isiprovided with ahorizontally disposed open-ended slot 43 for the reception of ahorizontally disposed wheel-like member 44 mounted on the lower end ofthe screw-rod 26. This wheel has a radial Vslot 45 for the reception ofthe finger 42, and a vertically disposed stop pin 4G to engage the sideof said finger.

By this construction it is manifest that by turning the rod 26 in theproper direction, the slot 45 in the wheel 44 carried by said rod willbe caused to register with the finger, so that by lowering vthe rod 26and wheel, the upper prong of the finger will pass through the slot 45,when by turning the wheel the prongs will stride the same, and thusprovide a connection between the finger and wheel or enlargement, thepin 46 serving as a stop.

By constructing the casing barrel-shaped, or with outwardly belliedwalls, it is manifest that that portion ot the cage 1S which extendswithin the casing, will be spaced from the walls of the latter. Thisarrangement provides a larger water-way below the valve and above theexit from the casing, thus equalizing the flow, causing a more regulardischarge of water through the waste opening. By this construction ofthe barrel, a more ornamental fitting is provided, and besides, it isbetter adapted for bufling and finishing than the ordinary casings orfittings having straight walls. Furthermore, by reason of the'barrel-shape of. the casing, the laterally disposed chamber thereof isbrought nearer to the center of the casing, as is obvious.

It will be understood that the vertical opening in the finger 29, aswell as the slot 3l therein, is somewhat larger than` the lower end ofthe screw-rod 2G, and projeetion 30, respectively, so as to permit ofslight lateral movement or adjustment of the member 29. In the modifiedform, the slot 45 is slightly wider or larger than the finger 42, whichof course will permit of a little play or adjustment of said finger whenlocated in said slot.
